# SEGA for Anima

SEGA anima is implementation of ["SEGA: Spectral-Energy Guided Attention for Resolution Extrapolation in Diffusion Transformers" (arXiv:2605.22668)](https://arxiv.org/abs/2605.22668) for Anima model in ComfyUI.

## Installation

### Using git

From root folder of ComfyUI, goto `./ComfyUI/custom_nodes` and open terminal or command prompt and type following:
`git clone https://github.com/Filexor/SEGA_Anima.git`

### Via downloading zip

Click green "\<\> Code ▾" button and then click "Download ZIP" and extract folder to `./ComfyUI/custom_nodes` .

### Via ComfyUI Manager

1. Open ComfyUI Manager and click "Custom Nodes Manager".
2. Find "SEGA for Anima" and install it.


## Usage

You can find "SEGA for Anima" node in "Add node" -\> "model" -\> "patch" -\> "anima"
Insert "SEGA for Anima" node to between "Load Diffusion Model" node and "KSampler" node.

### What should I do when output image is bad

1. If image does not appear, first thing you have to do is decreasing "training_resolution". Too low "training_resolution" results structual inaccuracy.
2. Adjust CFG. Normally, higher CFG is needed for high resolution output.
3. You may adjust "theta", "base_mscale_coefficient", "mscale_alpha" or "d_mul".
4. Creator of the this node does not know what rest of parameters do. You may do experience with those.
5. If changing none of above work, Increasing steps may work.
